A permit must be obtained to cross a levee within the Bossier Levee District (BLD). Permit applications for levee crossings do not require formal approval by the BLD Board of Commissioners; they are approved by the BLD administrative staff. Levee crossing permits are reviewed by BLD staff, La. Department of Transportation & Development (DOTD) and the U.S. Army Corp of Engineers. The purpose of the levee permit program is to evaluate all activities on or adjacent to levees in order to ensure that no action or activity is undertaken which would or reasonably might threaten the use, operations, maintenance, protection or integrity of the levees or its components and to establish controls which allow for legitimate non-threatening activity.
